Abstract

A constant contact side bearing assembly for a railcar includes a housing having a base, a pair of mounting apertures formed through a thickness of the base, a generally cylindrical housing wall upstanding on the base, a pair of diametrically opposed channels, a pair of diametrically opposed openings and a guide member disposed centrally on and upstanding from an inner surface of the base. A cap is disposed for reciprocal axial movement relative to the housing. An elastomeric spring is disposed within a generally closed chamber formed by a combination of the housing and the cap. A pair of air passages is provided for dissipating heat generated during operation of the constant contact side bearing assembly. Each air passage is defined by a pair of aligned openings formed through a wall portion of the cap. Each opening may be disposed within a pocket provided within the cap wall.
